EUGENE SOLOMON MANNY, OF MONTREAL, CANADA, ASSIGNOR TO HIMSELF, \VILLIAMROBINSON, AND ALEXANDER D. LANSKAIL, OF SAME PLACE.

HOT-WATER AND STEAM BOiLER.

SPECIFICATION forming part of Letters Patent No. 597,683, dated January18, 1898. Application filed May 12, 1397. Serial No- 636,199. (No modeh)Patented in Canada February 16, 1897, No. 55,014.

To all whom it may concern:

Be it known. that I, EUGENE SOLOMON MANNY, of the city of Montreal, inthe Province of Quebec and Dominion of Canada, have invented a new anduseful Improvement in Hotater and. Steam Boilers, (for which I haveobtained Letters Patent in Canada, No. 55,014, dated February 16, 1897,)of which the following is a full, clear, and exact description.

The object of my invention is to construct a sectional boiler of thevertical type adapted for use as a hot-water or steam boiler, whichboiler will be of simple and economic construction, and whereby theproducts of combustion will be consumed to the utmost and thecirculation of both heat and water in the boiler will be practicallyperfect.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical section through the upper portion of the improvedboiler, the lower portion being shown in side elevation. Fig. 2 is aplan view of the crown-section for the boiler. Fig. 3 is a plan view ofone of the intermediate sections of the boiler. Fig. i is a sectiontaken on the line 4: 4 of Fig. 1. Fig. 5 is a section taken horizontallyon the line 5 5 of Fig. 1. Fig. 6 is a plan view of an intermediatesection of the boiler, illustrating a modified form thereof. Fig. 7 is asection on the line 7 7 of Fig. 6. Fig. 8 is a section on the line 8 8of Fig. 3, and Fig. 9 is a section on the line 9 9 of Fig. 3.

A represents the ash-pit, B the fire-pot, and G the water-sections ofthe boiler, which sections comprise a crown-section 10, intermediatesections 11, and a bottom section 12. The fire-pot is provided with awater-space 15 and is enlarged at the top, the top portion of thefire-pot being given a downward and inward inclination, as shownparticularly in Fig. 1. The bottom water-section 12 rests upon thefire-pot, the intermediate sections rest upon the bottom section andupon each other, the crown-section resting upon the uppermostintermediate section, and a crownsheet 13 forms the top portion of theboiler, receiving the waste products of combustion, and this crown-sheetis in direct communica tion with the smoke-stack or oiftake-flue 14;.

All of the water-sections of the boiler are preferably circular ingeneral contour, and each section is further provided with an interiorchamber 16, adapted to contain water. Each water-section of the boileris also provided at the rear with two offsets 17 and 18, each of whichis provided with an opening 19, extending through from top to bottom.Between these offsets each of the water-sections is provided with a web20, so constructed as to receive bolts 21, said bolts serving to conneotone watersection firmly with the other, and when the variouswater-sections have been properly assembled the openings 19 in theboiler-oifsets 17 and 18 will form continuous passages adapted toreceive water, the water-inlet pipe being connected with the passage inthe oifset 18 of the crown watersection and the outlet water-pipe 23being connected with the passage in the ofiset 17 of the same section.All of the passages 19, as illustrated in Fig. 8, are in connection withthe water-chamber 16 of the section of the boiler to which the passagesbelong. Thus each water section has an independent inlet and anindependent outlet.

The crownsection 10 is provided at the back with an opening 24 and ateach side with a similar opening, (designated, respectively, as 25 and26,) the openings 25 and 26 being diametrically opposite. Each openingis inclosed or surrounded by a wall 27, which walls extend downwardbelow the bottom of the crown section, forming collars 28. Theseopenings 24, 25, and 26 are duplicated in each of the water-sections,and all the water-sections except the lowermost one, 12, are provid edwith the above-named collars 28. The crown-section 10 is otherwiseclosed at both top and bottom, but is provided with a deflecting-plate29, located about centrally therein, extending from the wall of the backopening 24. to within a predetermined distance of the front, asillustrated in Fig. 2.

The intermediate and the lowermost watersections differ from thecrown-section in that in the former a central opening 30 is made,

surrounded by a suitable wall, and in addition to the openings 24:, 25,and 26 series of openings 31 are made between the openings 24:, 25, and26; but the openings 31 extend only through the body of the sections andare not surrounded, as are the openings 24, 25, and 26, with thedownwardly-extending collars.

The collars 28 form spaces or chambers 32 between the various sections,and each intermediate section, as well as the lowermost section, isprovided with a deflecting-plate 33, corresponding in location to thedeflecting plate of the crown-sectiou. A pipe 34 is carried from thewater-inlet passage of the lowermost water-section into the water jacketor space 15 of the fire-pot, and a like pipe 35 is similarly carriedfrom the return water-passage of the lowermost section into thewaterjacket of the fire-pot, as illustrated in Fig. 1. The lowermostwater-section 12 instead of being provided with the collars 28 isprovided with an outwardl y-extendin g marginal flange 36 and acorresponding inner flange 37, forming an annular space 38 at the bottomof the said section, as shown in Figs. 1 and 5, the openings 24., 25,and 26 and the openings 31 in this lowermost water-section being all incommunication with the said space 38.

By inclining the upper wall of the the pot the annular chamber 38 at thebottom of the lowermost water-section may be readily cleaned by anysuitable instrument introduced through the door of the fire-pot. Vhenall of the water-sections are built one upon the other, the openings 24,25, and 26 will form continuous fines for the passage of the products ofcombustion from beneath the lower water-section 12 to the dome or spaceabove the crown section, and the central openings 30 of the intermediateand the lowermost water-sections will be in registry, as shown inFig. 1. Thus it will be observed that the products of combustion uponleaving the fire-pot will ascend through the central flue formed by theopenings 30, but cannot pass the crown-section, so that the hottestpoint in the boiler, except immediately over the fire-pot, will beimmediately beneath the crown water-section. As the products ofcombustion become cool they will descend through the openings 31, whichconstitute return-fines for the products of combustion, and afterentering the annular chamber 38 at the bottom of the lowermostwater-section these return products of combustion will ascend throughthe smoke-conducting fiues to the chimney, which latter fines are formedby the openings 24, 25, and 26, as previously stated.

In Fig. 6 l have illustrated a slight modification in the constructionof the intermediate water-sections. Under this construction the bottomplate of the section at each side of the center is struck up, forminginverted- V-shaped spaces 39, and in the top of the section, at thecontracted portion of these recesses, slots 40 are made. These slotspermit of the upward passage of the smoke, and the slots and spaces arepreferably of segmental form. These slots or openings also serve toprotect the water-sections against the effects of sudden expansion andcontraction.

Each water-section is provided with a marginal flange similar to theflange 36 of the lower section, and these flanges constitute one Wallfor the openings 24, 25, 26, and 31. hen the sections have beenconnected, the seams maybe filled in or covered with clay or a cementingmaterial of any description.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- 1. In a boiler, the combination, with a firepot, anda dome having an outlet for the products of combustion, ofwater-sections located between the fire-pot and dome, the intermediateand lower sections having central fireopenings over the fire-pot, andreturn and ofttake openings for products of combustion attheir sides,the crown-section being provided only with offtake-openings for theprodnets of combustion,communicating with those of the lowerwater-sections and with the dome, and means for circulating water insaid sections.

2. In a boiler, the combination, with a firepot, and a dome having anoutlet for the products of combustion, of a crown water-section havingopenings in communication with the dome, adapted to carry off wasteproducts of combustion, additional water-sections located beneath thecrownsection, each provided with a central fire-opening, return-openingsfor the products of combustion, the offtakeopenings adapted to carry offthe waste proclucts of combustion communicating with the correspondingopenings in the crown-section, spacing devices for the water-sections,and means, substantially as described, for circulating water in saidsections.
